Napier + Whanganui Councils data via eolas

This cluster covers two unrelated city/district councils that happen to publish via similar portals: Napier City Council (Hawke's Bay, ~67,000 people) and Whanganui District Council (Manawatū-Whanganui, ~50,000 people). eolas serves 20 datasets across both.

Why grouped? Both publish via the WhanganuiData portal pattern, sharing data-pipeline plumbing. They have no geographic or political relationship.

If you're doing Napier or Whanganui property research, urban-planning analysis, or coastal-region work — this is the source.

Common patterns

Napier heritage walk

import geopandas as gpd
heritage = client.napier_whanganui("napier_heritage_buildings", as_sf=True)
print(f"Napier heritage buildings: {len(heritage)}")
# Famous for Art Deco — most listings are 1930s reconstruction post-1931 earthquake
print(heritage[heritage["era"] == "Art Deco"].head(10))

Whanganui historic 1968 aerial coverage

aerial = client.napier_whanganui("wgnui_aerial_index_1968", as_sf=True)
# Index polygons + photo IDs — useful for historic-property research
print(aerial.head())

Source-specific notes

  • Napier is Art Deco: the 1931 Hawke's Bay earthquake destroyed central Napier, leading to rapid reconstruction in Art Deco style. The heritage-buildings layer is heavily 1930s — a key data product for the tourism + heritage sector.
  • Whanganui 1968 aerial: an unusual offering — most councils don't publish historic aerial indexes. Useful for historical-property research.
  • Two unrelated councils, one cluster: don't infer a relationship from the grouping. Both publish to similar portal infrastructure, which is why they pipeline together.
  • Napier also publishes other layers via the HBRC cluster: for regional-scale data (coastal erosion, liquefaction), see Hawke's Bay Councils.
  • Whanganui regional layers: for regional-scale data, see Manawatū-Whanganui Councils (Horizons + the wider region).
